'''PiggyPack''' by kristopolous is a very basic open source Ruby script for hiding data in 24-bit images.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Technical details ==&lt;br /&gt;
It uses the 8 LSB from each 24-bit RGB triplet (3 LSB from red + 2 LSB green + 3 LSB from blue)&lt;br /&gt;
&lt;br /&gt;
The header is&lt;br /&gt;
* 1 byte number specifying the length of the file name&lt;br /&gt;
* The filename itself&lt;br /&gt;
* 8 byte lsb number specifying the length of the playload&lt;br /&gt;
* The payload itself&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
